Leners Patent No. 113,712, dates April 11, 1871.

IMPRQVEMENT IN WASH-BOILERS.

`'.lhe Schedule .referredto in these Letters Patent and making part ofthe same.

To alt whom it 'may concern:

Be it known that we, WILLIAM A. WELLS, of St.Y Paul, in the county ofRamsey and State of Minnesota, and Linnenl l?. CONVERSE, of the city andcounty of Milwaukee and State of Wisconsin, have invented certainImprovements in Wash-Boiiers and we do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe annexed drawing making part of this specifica` tion, in which-Figure l is 'a vertical longitudinal section of our improvedwash-boiler.

' Figure 2 is a vert-ical transverse section thereof.

' Figure V3 is a horizontal section.

The same letters Aare used in all the gnres in the designation oi"identical parts.

rlhis invention relates to that class of washboilers which areconstructed with circulating dues or passages for conducting the heatedwater and steam from the bottom of the boilerto the top to be forceddownward through the clothes to be cleansed; and

Our improvement consists in .the construction of the clothes-supportinggrate, and its combination with the boiler, and also in4 the employmentof a siphonic faucet for' drawing the water from the boiler.

To enable those skilled in theart to make and use our invention, we willproceed to describe its construction' and operation.

The shell A'of the boiler is diminished vin size at the bottom in theordinary manner, to form the part A', which enters the stove-hole whenit is used.

Upon the shoulder thus formed in the interior of the boiler theclothes-supportin g grate or rack B rests, it being of such size that itmaybe readily inserted and removed.

This grate consists of a band of tin of the proper width, and suitablystrengthened around the edges by wires, which is provided with a seriesof perforations, I), along the upper edge, for the purpose of receivinga. strong cord, B', to he laced or woven in the manner clearly shown iniig. 3, so as to form a web or grating 'upon which the clothes may restto be held above the bottom of thc boiler.

As the cord or cords forming this web must be drawn 'very taut the handof tin is provided with braces b1 between its sides, to prevent itscollapsing ou thus drawing the cords.

A vertical passage, O, is formed upon each of the parallel sides of theboiler by a plate, O', soldered at its ends to the rounded ends thereof,and on top by a flange to the side.

The passage is open at the lower end, which extends to just below theupper edge of the supportinggrate, and near the upper end itcommunicates with the interior of the boiler by a series of port-s, c o,the which in one plate C should be diagonally opposite to those in theopposite plate C', so that the jets of hot water and steam may not meeton issuing therefrom.

Perforations b2 in the band of the supporting-grate permit of thepassage of the heated water and steam from below the clothes up into thepassage O, from .which such water and steam issues at the top upon thetop of the clothes, in passing through which the dirt is carried down tothe bottom.

The lid D is secured by passing one end of it under a fixed cross-band,secured to the shell of the boiler, and couning its other end by ahinged catch, d', as shown clearly in iig. 1.

A vertical pipe, E, is arranged iu one end of the boiler, through which'cold water can be conducted to the bottom of the boiler when inoperation without passing it through the clothes.

F is the faucet used to draw the dirty water from the boiler in orderthat clear water may take its place in completing the cleansing process.This faucet is a siphou with its short leg which enters the boilerextending down to Very -near the bottom thereof', so that it can drawofi` all the water without tilting the boiler.

Vhat we claim as our invention, and desire to securev by Letters Patent,is-

In combination with a wash-boiler constructed substantially as hereindescribed, the removable clothessupporting rack, composed of metallicrim B and intel-laced cords B', and the siphonic faucet F, as and forthe purposes set ibi-th.

' In testimony of our inventionwe have hereto set our hands.
